Polyphony Digital will commemorate 15 years of Gran Turismo with its sixth edition, due for release this July. While it might be disappointing to some who were banking on the title making its way to the PlayStation 4, the accuracy of the physics behind the cars and tracks featured in GT6 should still be enough to impress players. In addition to the updates to the graphics and physics engines that will push the limits of the now seven-year-old PS3, GT6 will also launch with a roster of 1,200 cars, 33 locations and 71 track layouts.
